Hello,
Im trying to make a micro-game where squares are falling from the sky and you have to avoid them and get to the top. if you make it to the top, an image will appear congratulating you. If you run into another square, however, an image will appear telling you you lost. I can't figure out how to code the collision though. Any ideas?
2. /* preload="grid.jpg" */
3. /* preload="sheen.jpg" */
4. /* preload="losing.jpg" */
6. PImage losing;
7. PImage sheen;
8. PImage grid;
9. int[] rectX = {10, 36, 63, 185, 210, 250, 340, 375, 300, 400, 460, 460, 475, 520, 555, 600, 625, 655, 725, 150, 770, 680};
10. int[] rectY = {10, 690, 320, 28, 165, 730, 385, 75, 610, 15, 280, 565, 700, 35, 360, 200, 450, 630, 350, 400, 30, 700};
11. int rectSize = 25;
12. int playerX = 400;
13. int playerY = 775;
14. int edge = 2;
15. int inner = edge;
17. void setup() {
18. losing = loadImage("losing.jpg");
19. sheen = loadImage("sheen.jpg");
20. grid = loadImage("grid.jpg");
21. size(800,800);
22. image(grid, 0, 0);
24. }
26. void draw() {
27. fill(255); //player avatar & glow effect
28. strokeWeight(2);
29. stroke(134,250,255);
30. filter(BLUR);
31. rect(playerX,playerY,20,20);
32. playerX = constrain(playerX, inner, width - inner);
33. playerY = constrain(playerY, inner, height - inner);
38. fill(0); //AI avatars
39. strokeWeight(3);
40. stroke(255,145,6);
41. for(int i = 0; i < rectX.length; i++){
42. rect(rectX[i], rectY[i], rectSize, rectSize);
43. rectY[i]+=25;
44. rectY[i]%=height;
45. if(playerY < 5){
46. image(sheen,0,0);
47. }
49. }
50. }
54. void keyPressed() {
55. if (keyCode == UP) {
56. playerY = playerY - 7;
57. }
58. if (keyCode == RIGHT) {
59. playerX = playerX + 7;
60. }
61. if (keyCode == LEFT) {
62. playerX = playerX - 7;
63. }
64. if (keyCode == DOWN) {
65. playerY = playerY + 7;

Hi, I'm making microgame program where you control one square and there are other uncontrolled squares bouncing around and you have to avoid them. However, all my AI squares are listed in an array and constrain() won't allow the use of an array? Help, please!
2. /* preload="grid.jpg" */
4. PImage img;
5. int[] rectX = {10, 36, 375, 475, 600, 680, 150, 770};
6. int[] rectY = {10, 690, 165, 700, 200, 490, 400, 30};
7. int rectSize = 25;
8. int playerX = 400;
9. int playerY = 400;
10. int edge = 2;
11. int inner = edge;
12. int aiX =
13. int aiY
15. void setup() {
16. img = loadImage("grid.jpg");
17. size(800,800);
18. image(img, 0, 0);
20. }
22. void draw() {
23. fill(255); //player avatar & glow effect
24. strokeWeight(2);
25. stroke(134,250,255);
26. filter(BLUR);
27. rect(playerX,playerY,20,20);
28. playerX = constrain(playerX, inner, width - inner);
29. playerY = constrain(playerY, inner, height - inner);
32. fill(0); //AI avatars
33. strokeWeight(3);
34. stroke(255,145,6);
35. for(int i = 0; i < rectX.length; i++){
36. rect(rectX[i], rectY[i], rectSize, rectSize);
37. rectX = constrain(rectX, inner, width - inner);
38. rectY = constrain(rectY, inner, height - inner);
40. }
41. }
43. void keyPressed() {
44. if (keyCode == UP) {
45. playerY = playerY - 3;
46. }
47. if (keyCode == RIGHT) {
48. playerX = playerX + 3;
49. }
50. if (keyCode == LEFT) {
51. playerX = playerX - 3;

I'm trying to make a very very dumbed down MS Paint program where when you select any of the three colors and click and hold down, a circle or "brush" will appear with the color of which you just selected. Totally stuck. Any suggestions?
2. int red;
3. int redX = 200;
4. int redY = 30;
5. int redSize = 35;
6. int green;
7. int greenX = 400;
8. int greenY = 30;
9. int greenSize = 35;
10. int blue;
11. int blueX = 600;
12. int blueY = 30;
13. int blueSize = 35;
14. color currentColor;
17. void setup() {
18. size(800,800);
19. background(random(255),random(255),random(255));
20. frameRate(60);
21. red = color(255,0,0);
22. green = color(0,255,0);
23. blue = color(0,0,255);
24. }
26. void draw() {
28. fill(red);
29. ellipse(redX,redY,redSize,redSize);
30. fill(green);
31. ellipse(greenX,greenY,greenSize,greenSize);
32. fill(blue);
33. ellipse(blueX,blueY,blueSize,blueSize);
34. }
36. }
39. if (mousePressed && mouseButton == LEFT); {
40. noStroke();
41. fill(currentColor);
43. if (mousePressed && mouseButton == LEFT); {
44. if ((mouseX > redX) & (mouseY > redY) & (mouseX > redX + redSize) & (mouseY > redY + redSize)){
45. currentColor = color(red);
46. }
47. }

Falling effect?

Ok, so let me begin by saying that I am completely new to programming and in this class i'm taking we were kinda just thrown into coding and are expected to know what we're doing. The class is more researching to figure out how to code than it is actually learning how to do the coding. Anyways, I am trying to make a falling effect; sort of like the famous matrix letter falling thing. But mine is much simpler. I just want there to be squares to fall in straight columns from the top to the bottom. I can probably take on any other slight modifications from there, but i don't even know where to start. I'm looking for a mentor to walk me through the steps necessary to take to get this end product. Any takers, please??
